libvirt users - Nov 2021 - how to use vhost-user-vsock

Hello community,

  I am looking for a way to configure vhost-user-vsock using libvirt, but
looks like it is not written in doc. How can I use vhost-user-vsock using
libvirt? Thank you.

Libvirt has basic support for vsock:

https://libvirt.org/formatdomain.html#vsock

For instance the following:

    <vsock model='virtio'>
      <cid auto='no' address='4'/>
    </vsock>


will get you:

-device
'{"driver":"vhost-vsock-pci","id":"vsock0","guest-cid":4,"vhostfd":"6789","bus":"pci.0","addr":"0x7"}'

But, I don't think we have vhost-*user*-vsock implemented yet.
